where to find rubber boot for door locks?

I need a new rubber boot for one of my solenoids for my door poppers. The old boot tore and now every time it pops the door then releases the plunger, it pops out of the solenoid housing. Where can I find a new rubber boot?

The label on the solenoid says:   Amenity Sil-40

Any IDeas?

Thanks

I found out that it is from SPAL USA. I found there website and sent a request to their support email in hopes of finding a replacement boot. I will let you know what happens. In the mean time if someone knows please don't hesitate t opost.

The current congifuration seems to be the only one that will allow the door handle to be pulled completely open.

At any rate, I ended up shooting an email to SPAL's customer service through their website, and asked where I could buy a boot. They emailed me back the next day and asked for my mailing address. They shipped two boots out right away at no charge! That's pretty dam cool. I'll put them in tonight and see if it fixes the problem.

As it turns out the boots fixed the problem. That rubber boot is in fact what keeps the rod from coming out of the solenoid body. after some research I found this a a common problem for the SPAL solenoids, these boots crack and split all the time. I have aslo found that there are much better built solenoids available by other companies. If these go ever fail completely I will definetly find something different.
